SEPARATOR.

Application filed. December 15, 1913.

To aLZ whom it may concern Be it known that I, JOHN M. ALLEN, a citizen of the United States, residing at Anaconda, in the county of Deerlodge and State of Montana, have invented a new and useful Separator, of which the following is a specification.

This invention relates to separators, one of its objects being to provide means whereby substances of three difi'erent grades can be quickly and efliciently separated according to their specific gravities. For example, where the material to be treated consists retained in a receptacle provided therefor.-

A further object of the invention is to provide improved means for effecting the separation of the material and additional means whereby the ore may be conveyed from its receiver to a spout designed to direct it into the crusher.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :-Figure 1 is a plan view of the separator. Fig. 2 is a section on line AB Fig. 1. Fig. 3 is a section on line CD Fig. 2.

Referring to the figures by characters of reference 1 designates a semi-cylindrical receptacle in one end of which is journaled a shaft 2 adapted to be driven in any suitable manner. This shaft is secured to the center of a disk 3 which lies close to said end wall of the receptacle 1 and extends downwardly into the receptacle, the periphery of the disk Specification of Letters Patent.

lying close to the bottom of the receptacle as shown particularly in Fig. 3. Extending perpendicularly from one face of the disk 3 are V-shaped buckets. or scrapers 4, the length of these buckets being substantially equal to the length of the interior of receptacle 1 so that each bucket will extend from disk 3 up to and almost in contact with that end of receptacle 1 remote from disk 3. Any desired number of these buckets or scrapers 4 may be used and the same are located close to the periphery of the disk. An outlet spout 5 extends from one side of the receptacle 1 and the scrapers 4: are designed, when disk 8 is rotated, to engage material resting on the bottom of receptacle 1 and drag it upwardly to the upper end of spout 5 where it will be discharged into the spout. The scrapers or buckets 4: are so positioned that, when they are in position to deliver material to the spout 5, the bottoms of the delivering buckets. will lie substantially in the same plane with the bottom of the spout 5. In this connection see Fig. 3 of the drawlngs.

Mounted upon that end of receptacle 1 remote from disk 3 is an inclined sluice 6. A receiver 7 is supported above the bottom of the receptacle 1 by an arm or bracket 8. A feed chute 9 is inclined downwardly and is adapted to direct material into the top of the receiver 7. A feed pipe 10 extends into one end of the receptacle 1 and has a nozzle 11 extending upwardly into the bottom of the receiver 7.

In operation the disk 3 and shaft 2 are to be driven in any suitable manner so that the buckets 4 will successively scrape along the bottom of the receptacle 1 and elevate to the spout 5 any material which may be in the path of the buckets. The material to be separated is supplied to the chute 9 and gravitates therealong into the upper portion of receiver 7, which receiver is filled to its upper edge with water supplied thereto from the nozzle 11. Ihis water is constantly draining over the upper edge of the receiver and into the inclined receptacle. When the material is directed onto the sur face of the water, the heavier values gravitate to the bottom of the receiver 7 while the lightest substances or, in the present instance, the wood particles, will float with the overflowing water into the receptacle and then out through sluice 6. The lighter value which is in the form of the ore to be crushed will strike the surface of the water and be held in suspension by the ascending water current so as to float into the receptacle l where the moving buckets or scrapers 4 will engage it and carry it upwardly to the spout 5. From this spout the ore can be directed into crushers provided therefor.

What is claimed is 1. A separator including a'receptacle, a receiver supportedtherein, means for directing a fluid upwardly within the receiver, means for directing material by gravity onto the surface of the fluid contained in the receiver, said receptacle constituting means for receiving material floating on the water in the receiver and heavier material held in suspension by the ascending current, a sluice below the level of the receiver for receiving the overflow from the receptacle and the floating material in the receptacle, a disk mounted for rotation in one end of the receptacle, combined scrapers and buckets movable with the disk to points below the sluice for directing upwardly from the receptacle the heavy material discharged thereinto from the receiver, and a chute extending from the receptacle for receiving such material from the buckets or scrapers, each of said buckets or scrapers being substantially V-shaped and extending lengthwise of the receptacle.

2. In a separator, the combination with a receptacle substantially semi-cylindrical, a receiver supported in the upper portion of the receptacle, means for directing water upwardly within the receiver, of means for directing material by gravity onto the surface of the water in the receiver, said receptacle constituting means for receiving the overflow from the receiver and the light material floating on the surface of the water in the receiver and the heavier material held in suspension by the ascending water current, a sluice below the receiver for receiving the overflow from the receptacle and the lighter material floating in the receptacle, a disk mounted for rotation in one end portion of the receptacle, and combined scrapers and buckets extending from one face of the disk and longitudinally of the receptacle and movable below the sluice for engaging the heavy material discharged into the receptacle, each bucket being substantially V-shaped and inverted while in active position, and a chute for receiving material from the buckets or scrapers.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two witnesses.

JOHN M. ALLEN.
